To all @07mm it may concern Be 1t known that I, ROBERT H. ylloADAJus, a citizen of the United States, residing at Due West, in the county of Abbeville and t State of South Carolina, have invented a new and useful Automatic Reservoir-Forming Plow, of whichthe following isa specification.

The invention relates to an automatic reservoir forming plow.

YThe objectof the present inventionis to improve the constructionof plows, and to provide a simple, eflicient and comparatively inexpensive plow 'designed for the cultivation ofrcotton, corn and other plants, and equipped with means for automatically lifting a plow proper or furrow opening device to providea series of reservoirsor furrow sections separated by intervening dams, and adapted to catch and hold the water, which might otherwise runl olf the ground.

With these and other objects in View, the invention consists in the constructionY ,and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings', and pointed out inthe claims hereto appended; it being understoodthat various changes in the form, proportion, size andfminor, details of construction, within the scope of the claims, may be resorted to without departing Afrom the spirit or, sacriiicing any of the advantages ofthe invention.

F ig. 5 is a longitudinal sectionview ofva twoghorse automaticreservoir formillgplow. 6 is a plan view of the same.

Likelnumerals of reference designate cor-` responding parts in all the figures of the drawings.

In Figs. 1 to 4 inclusive ofthe accompanying drawings, the inventionisshown appledtoaonehorse plow comprlsingia subv3 adapted lto be automatically lifted bythe means hereinaftergdescribed to raise a furrow -opening device4 aosufiicient distance above the bottom of the furrow to leave unplowedI or dam portions and form a series of furrowsections or reservoirs separated by the said dam portions and adapted to catch and hold water.' The main frame, which may be constructed of any suitable material, is composed lof spaced sides and connecting front and rear portions 5 and 6, the vfront portion being preferably curved, as shown, and provided with a draft hook 7 or other suitable means for the attachment of a swingletree. The rear` transverse connecting portion 6 is preferably stra-ight and its terminals are suitably connected with the side barsof the Vframe. The carrying wheel 2, which is located in advance of the furrow opening device ,4, is .preferably provided with a broad rimer periphery, as shown, and it is mounted centrally on a shaft or axle l.8, which issuitably secured at its terminals tothe sides, of the main frame 1.

he plow beam .3, which is preferably constructed of metal, is provided at the yfront endwith a head or. enlargement 9 having a pluralityy of perforations `10, arranged at intervals in substantially a vertical Series and adapted to receive atransverse pivot rod 11, which is secured at its terminals to the sides ofthe frame near the front transverse connecting portion 5 thereof.' The pivot 11, which is `adaptedto be arranged in any one of theperforations 10, is provided at oppositesides of the head '9 with set collars 12, adapted to retain the plow in a central position on the transverse rod 11. The pivot and theperforationspermit an adjustment of the plow beam to secure agproper set of the same. The plowbeam is provided at a point intermediate of its ends with an oblong opening 13, receivingthe wheel 2 and composed of spaced sides and front and rear connecting portions formed integral with the sides and with the ffront and rear portions of the plow beam. The rear -portion of the plow beam extends beyond thereaiyend soy of the main frame l and curves downwardly and forwardly, and the furrow opening device 4 is suitably secured to the said rear portion of the beam 3.

ln the accompanying drawings, the furrow opening device is shown in\the form of a double moldboard share consisting of two straight angularly disposed blades, but any other form of furrow lopening share or device may be employed, and the plow may be equipped at the front with a suitablev `colter 14, secured to the lower end of a front standard 15, which is attached at its upper terminal to a substantially horizontal plate 16. The horizontal plate, which is approximately segmental to conform to the configuration of the front portion of the main frame 1, is provided at opposite sides with spaced lugs 17, vwhich are riveted or otherwise secured to the inner faces of the sides and front portion of the main frame.

rlhe plow beam is provided at opposite sides of the central oblong wheel receiving portion with inwardly extending projections or flanges 18 arranged in the path of a pair of laterally projecting lifting tappets 19, mounted on one of the spokes 20 of the wheel 2 and adapted at each revolution thereof to engage beneath the projections or flanges. 18 of the plow beam and lift the` latter from'the furrow. `The lifting tappets in the forward rotation of the wheel are carried from beneath the flanges or projections 1.8 and the plow beam is permitted to drop and rengage the furrow forming device with the soil. The projections or flanges 18 are carried by rectangular sleeves 21, arranged on the spaced side portions of the plow beam and adjustably secured to the same by set screws 22, piercing the outer ,walls of the sleeves and frictionally engaging the beam. The laterally projecting lifting tappets 19 are carried by a cylindrical sleeve 23, which is secured at the desired adj ustment on the spoke of the wheel by a set screw 24. The flanges or projections of the beam and the lifting tappets of thewheel are adapted to be adjusted to secure the desired lifting action and to vary the height to which the beam is elevated in the operation of the plow. The `lifting tappets may be mounted on one or more of the spokes of the wheel to vary the interval between the lifting operations of the plow beam and the consequent length of the furrow sections or reservoirs, and various equivalent means may be employed for lifting the plow beam and timing such operations thereof.

The plow beam is equipped with an oscillatory locking device adapted to hold the plow beam rigidly against upward movement while the furrow vopening device is in engagement with the soil, and it is composed of spaced side rods 25 and a connecting top portion 26, which is pivotally mounted in an l per edges of the sides of the oblong portion I of the plow beam when the oscillatory locking device is in a vertical position and in engagement with the said beam, as illus.

trated in Figs. 1 to 3 of the drawings. rlhe oscillatory locking device may be-pivotally mounted in the support 27 in any preferred manner. ln the accompanying drawings the top connecting portion 26 of the locking device is tubular and a rod 26a extends through the tubular portion 26 and is adapted to bel arranged in any pair of a plurality of perforations 27 in the upper portions of the sides of the support 27. The rod 26a is provided at the end with a head and is threaded at the other end for the reception of a nut, and the perforations 27L permit a vertical adjustment of the oscillatory locking device to adapt the same to be arranged in operative position to engage with the plow beam when the latter is adjusted'or limited in its downward movement to vary the depth of the furrow, as hereinafter fully explained. rllhe sides of the support 27 are suitably secured at their lower ends to the side bars of the main frame, and the plow beaml is provided at opposite sides of its oblong portion with projecting lugs 29, located in rear of the arms 2S, which extend inwardly at the lower terminals of the side rods 2,5. rllhe locking device is maintained in contact with the upstanding stop lugs 29 by a coiled spring 30, secured at its front end to one of the side rods 25 and connected' at its rear end to the main frame in rear of the support 27 The locking device, which straddles the wheel, is equipped at opposite sides with adjustable projections or flanges 31, arranged in the path of a pair of laterally projecting beam releasing tappets 32, mounted on one of the spokes of the wheel and arranged to engage the projections or flanges 31 just prior to the time when the lifting tappets engage with the projections or flanges 13 of the plow beam, so that the plow beam will be unlocked and freeto be raised by the lifting tappets 19. The projections or flanges 31, which extend inwardly from the side rods of the locking device, are carried by sleeves 33, adjustable upwardly and downwardly on the said side rods and secured to the same by set screws 34. The beam releasing tappets are also carried by a cylindrical sleeve 35, which is adjustably secured to one of the spokes of the wheel 20 by a set screw 36. 'lllienumber of beam reid'tifeso l leasing tappets will in practice correspond with the number of lifting tappets and will be arranged to release the beam prior to the lifting thereof.

The plow' beam is guided in its vertical l movement by a pair of vertical bars 38, se-- tion of the main frame with a cam 39, located beneath and adapted to lift the plow beam and mounted on a transverse shaft 40 journaled in suitable bearings of thevsides of the main frame and having an operating arm or lever 4l at one end for rotating the shaft to swing the cam upwardly and down-y wardly. The cam is adapted to maintain the plow beam in an elevated position out of contact with the ground, and it is also adapted to serve as an adjustable stop for limiting the downward movement of the plow beam to vary the depth of the furrow sections or reservoirs. lt is locked in its adjustment by means of a dog 0r detent d2, mounted on the operating arm or lever eil and arranged to engagea toothed plate 43 and connected with a latch lever -f, ar-` ranged adjacent to an upper handle portion of the operating arm or lever al. |lhe toothed plate lf3 is iiXed to the frame l at one side thereof. 'lhe oscillatory locking device is adjusted upwardly when the cam is adjusted. to limit the penetration of the furrow opening device', and the adjustment of thej oscillatory locking device enables the sides thereof to engage properly with the lugs 29 of the side portions of the beam in `the various adjustments of the cam 39.

ln Figs. 5 and ofthe drawings is illustrated a two horse plow comprising a frame 45 having a draft beam or tongue 46 and composed of spaced sides 47 and a transverse connecting portion 48. The sides are provided at their rear ends with suitable bearings for the receptionv of a rotary shaft or axle i9 of a pair of'carrying'wheels 50. The tongue vor pole d6 preferably extends rearwardly to the shaft or axle i9 andis supported by the same, and the said shaft or axle is provided at Yopposite sides with curved lifting arms 5l, arranged to engage and automatically lift plow beams 52 pivoted at their front ends 53 to the transverse connecting bar or beam of the frame d5 and equipped with suitable furrow opening shares or blades 5ft and adapted to be altern nately lifted lby the arms 5l. The plow may Y be equipped with any number of pivoted beams and lifting arms, and the latter will be arranged to alternately lift .the plow beams so that the 'furrow' sections or reser-v voirs of theedj acent rowswill be Slaggered to eec-t a more uniform distribution of any water contained withinthem;

The one horse plow illustrated in lfigs. 1 to 4 inclusive of the drawings is provided with suitable-handles 55, secured to thesides. of the main frame and extending upwardly and rearwardly' therefrom. ln the form A of invention shown in Figs. 5 and 6 of the v drawings, the riding plow is provided with a suitable seat '56 havlng a standard secured to the `tongue `or pole and Aextending upwardly and rearwardly therefrom, the seat being located in rear of the shaft or axle 49.
